导语：
本文主要介绍了关于python定义数值类型变量的方法的相关知识，包括python lambda函数，以及python变量的数据类型有哪些这些编程知识，希望对大家有参考作用。
说明
1、Python内置了很多数值类型，其中常用的有int和float。
2、var1是int类型的变量，对应数学中的整数，取值范围为(-inf,inf)，即大。
实例
>>> a = 100
>>> type(a)
<class 'int'>
>>> b = 10**1000
>>> b
10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
